First, stimulate interest and create a good atmosphere for innovation.

Thinking is the driving force of innovation to stimulate students' innovative thinking motivation. In teaching, teachers should first explore the factors of innovative thinking in textbooks, be good at igniting the fire of innovative thinking and stimulate students' enthusiasm. Bruner, an American psychologist, once said, "The best stimulus of learning is interest in your subject." Indeed, a strong interest in learning can make students have a strong thirst for knowledge, thus having keen thinking, rich imagination and solid memory. The active participation of students is a conscious action. If they are not interested, they cannot take the initiative, and participation is even more empty talk. Therefore, teachers should strive to create teaching situations, so that students can actively think in the background provided by teachers, thus stimulating students' curiosity, fully mobilizing their enthusiasm for learning, allowing them to actively participate in the whole process of learning, and making the classroom interesting, interesting and interesting.

Second, inspire imagination and cultivate students' innovative spirit.

Imagination is the wing of creation, the basis of cultivating students' divergent thinking in teaching, and the indispensable basic thinking method of cultivating ability and developing creativity. Einstein said: "Imagination is more important than knowledge, because knowledge is limited, and imagination summarizes everything in the world, promotes progress and is the source of knowledge progress." Indeed, imagination can be said to be the gymnastics of thinking, and it is the internal motivation to expand the thinking space. Therefore, teachers should let students spread the wings of association in class, which is conducive to the cultivation of students' creative thinking ability.
